VACUUM OIL TREATER.

Application ed Mayl, 1926. `Serial No. 110,235.

rlhis invent-ion relates to pumpsand more particularly to deep oil well pumps. l

One of the important objects. of the invention is the provision of means associated` with the gas anchor pipe for separating the water enteringrwith the oil therefrom during` the operation ofthev working valve.

Another object of the invention is the provision of a nipple of a lesser diameter than the gas anchor pipe and the entrance pipe connectedA with the lower end of the nipple whereby when the liquid is forceably drawn through the nipple the' water will be caused to separate from the oil. Y

A further object of the invention is the provision of means for connecting the nipple, entrance pipe and gas anchor pipe together whereby these parts will be efliciently connected and spaced from the tubing anchor pipe at all points to permit the free flow of the-liquid around the gas anchor pipe,-

nipple and entrance pipe. Y

/Vith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings in which a preferred embodiment of the invention is shown.

Figure 1 is a side elevation of the proved device,

Figure 2 is a central longitudinal section through the same,

Figure 3 is a horizontal section taken on line 3 3 of Figure 1, looking in the direction of the arrows, and

Figure 4t is a horizontal section taken on line 1 -4f of Figure 1 looking in the direction of the arrows and illustrating the arrangement of the nipple within the tubing anchor pipe. l

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the numeral 5 designates the lower end of the barrel of the usual pump to which is connected by means of al collar 6, the depending tubing anchor pipe 7. In accordance with this invention the lower end of the pipe 7 is closed by a suitable cap 8. Directly below the coupling collar 6, the tubing anchor 7 is provided with a plurality Vof entrance openings 9 for permitting the lowof the oil into the same. v

rlhe collar 6 at a point between the barrel 5 and the tubing anchor 7 is provided with an internal annular flange 1() provided with a seat 12 forthe reception of the lower tapered end 13 of the standing valve casing '14. This casing 14- is provided with a valve seat 15 on which is adapted to normally resta ball valve 16.A The upperpend of the casing 14 has connected therewith the usua garbutt rod 17 for permitting of the connection thereof to the working valve, wherebj. the standing valve can be conveniently pulled when necessary.

The lower end of the casing L1 is internally threaded for the reception of the upper end of thegas anchor pipe 18 which ef;- tends centrally into the tubing anchor pipe 7. The gasanchor pipe 18 extends below the entrance openings 9 and in accordance with this invent-ion has connected thereto an elongated nipple 19 by a suitable couplingcollar 20. The bore of the nipple 19 is of a considerable lesser diameter than the gas anchor pipe 18 for a purpose which will be hereinafter more fully described.

The lower end of the nipple 19 has connected thereto, by a suitable coupling 21, an entrance pipe 22 which is of a greater internal diameter than the bore of the nipple 19. It is preferred that the internal diameter of the entrance pipe 22 be the same as the internal diameter of the gas anchor pipe 18. In actual practice, in one use of the device, a nipple having a three-eighths inch diameter will be used in conjunction with gas anchor pipes and entrance pipes having a diameter of three-fourths of an inch.

In operation the oil and water will flow into the anchor tubing 7 and will gravitate to the lower end thereof. The operation of the working valve will cause a suction or vacuum in the nipple 19 and owing to the decreased diameter of the nipple 19 over the gas anchor pipe 18 this suction will be considerably increased. The oil and water will be drawn into the entrance pipe 22, thence into the nipple 19 and then into the gas anchor pipe 18. The rush of the liquid in the nipple 19 will cause the separation of the oil and water and these ingredients are then carried to the surface in the ordinary manner.

Changes in detail may be made without departing from the spirit or the scope of this invention.

-I claim:

1. In an oil well pump, the combination 1 Ott with a barrel; for receiving the working valve, a tubing anchor depending therefrom,

than said gas anchor pipe connectedy there.

with. A

i2.l In an oil well pump, the'coinbination with a barrel for receiving the working rali" a standing Valve, and a gas anchor pipe depending from the standing valve, of a nipple of lesserdiameter than said gas anchorpipe connected' therewith, and an entrance pipe ofV greater diameter than the said nipple cennected 'with the lower end of the nipple.

In an oil well pump, the combination with a barrel for receiving the working valve, a tir-hing anchor depending therefrom, a standing Valve, and a gas anchor pipe depending frein thestanding valve and communicating with 'the casing thereof, of an oil and water separator connected with the gas anchor pipe at the lower end thereof including` means for contracting the'liqnid e, tubing anchor depending therefrom,

prior to the entrance thereof into the gas anchor.

et. In an oil well pump, the combinationl with` barrel, aiv tubing anchor connected therewith and depending therefrom, a cap closing the lower end of the tubing anchor, said anchor having` a plurality of liquid entrance openings adjacent to the upper end thereof, a *standing Valve arranged in Vthe barrel adjacent tov the lowery end thereof, and a gasY anchor pipe extending axially into the tubing anchor below the; entrance' openings thereof and communicating with the casing of the standing Valve, an elongated nipple detachahl'y connectedwith the lower end of the gas anchor pipe and'V having` an internalv diameter lesser than the internal diameter of the gas anchor pipe, anV

entrance pipe of Substantially the same internal diameter as the gas anchor pipe cn nectcd with the lower end of the nipple and terminating adjacent tosaid cap. i

In testimony whereof I affix my signature.
